2 Claims,

adjoining rails of each slidable frame and its coacting pivoted sash frame with cooperating vertical rectangular extensions facing each other and contacting in a plane and with their vertical junction extending beyond the middle of the sash frame; the rails at the opposite face-contacting in a. single plane and causing the said single plane face of the rails to conceal said extensions.

Another object of this invention is to provide one of said rails with a hollow circular cavity to receive the central end portion of the extension from the adjacent rail so as to permit the sash frame to swing to an obtuse angle considerably greater than ninety degrees from full open to full closed position.

Another object of this invention is to mount coil springs on the pivots of the said sash frames, the said coil springs being anchored at one end in the pivots and at the other end in a metal sleeve in the opposite rail, the said spring'and pivot causing the sash frame to be automatically securely locked 'in either open or closed position within the range of the sash movement.

Another object of this invention is to provide a locking bolt adjacent the pivot in one of the rails and to provide two holes in the opposite rail, the holes being on opposite sides of the pivot and providing means whereby the swinging sash `frame may be locked in reversed or open position, or in the normally closed predetermined position.

Another object of this invention is to provide a cut-out portion in the lower face of the window frame lower than the window sill, the Lsaid cutout portion being of suflicient depth to permit the upper slidable frame to enter therein and causing the upper surface of the upper slidable frame to be below the lower surface of the lower slidable frame when in topmost raised position and permitting the swinging of the upper sash frame at a convenient low operating level.

Another object of this invention is to provide a ring-shaped handle on the swinging sash frame of the upper slidable frame, the handle being set in a recess in the swinging sash iframe so as to be iiush with the upper surface of the said swinging sash frame and to permit the upper slidable :frame to be lowered without'encountering obstruction in its movements from the lower slidable frame.

With the above and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawings and pointed out in the claims which form part of this speciilcation.

Reference will now be had to the drawings, wherein like numerals of reference designate corresponding parts throughout the several views, in which:

Figure 9 is a cross-sectional view of two coacting rails, the section being taken as on line 9 9, in Figure 1.

In the illustrated embodiment of the invention, the numeral III indicates a. window frame having double hung slidable frames and comprising an upper slidable frame II and a lower slidable frame I2.

' The slidable frames I I and I2 have upper rails I3 and lower rails I4. Mounted in the slidable frames II and I2 are sash frames I5 and I8, having upper rails I'I and lower rails I8. o

The sash frames I5 and I6 are mounted on pivots I9, preferably xed in the upper rails Il and in the lower rails I8 of the sash frames. The upper rails I3 and the lower rails I4 of the slidable frames II and I2 have apertures 20 designed to receive the pivots I9 in fully housed relation and for free rotation therein.

The slidable frames have vertically positioned rabbeted openings 2I, 2|', serving to receive vertically positioned flanges or extensions 22,

22', on the sash frames. The sash frames may thus be swung into open or closed positions with respect to the slidable frames.

In order to provide rain and snow proof Junctions at the pivoted rails, I lhave rabbeted the rails so as to form right-angular steps in each rail. The steps interlock when the sash frames and the slidable frames are in closed position. I have thus divided the rails at substantially the middle of their horizontal depth and have formed upright walls or vertical extensions at the said middle of the rails which form a barrier to the passage of rain and snow. In order to make possible the pivotal mounting of the sash frame inside the vslidable frame, I have vformed each rail with a portion of the said-upright wall. As shown in the drawings, the rail I3,has` a vertical rectangular extension or tongue 23. The rail I1 has 'a vertical rectangular extension or tongue 24. The tongues are positioned on the outer face 23 of the window. f The rectangular extensions 23, 24, terminate in spaced-apart planes. The adjoining faces of the rails I3 and I1, at the inner face 2B ofthe window III, lie vin a single plane, as best shown in Figure l. y

The extenson 24 on the rail I1 stops short of the middle of the length of the sash frame and short of the pivot I9. The extension 23 on the rail I3 extends beyond the middle of the length of the sash frame, beyond the pivot I9. VThe line of abutment 29 of the two extensions makes an angle with the lengthwise sides `oi? the rails.

This angular relation of the extensions on the rails facilitates the relative rotation of the rails and furtherserves to augment the tightness of the iunctionof the .extensions 23, 24 against the passage of rain, snow, etc. between therails and into the room. 1

As best shown in Figures 3, 'I and 9, it will be noted that the rail I1 has a substantially semicircular cavity'21, the bottom surface vof which lies in the'same plane 33 in the rail I1 with which'the tongue 24 comes in juncture. lEach cavity 21 serves to receive the central vend portion 23 of the extension or tongue 23 from the adjacent or o o-acting rail I3.

I facing the room the extensions are not visible.

As will be noted from the drawings,v theexltensions 23, 24 have been made of substantially rectangular form, each one occupying substantially one-half the depth of a rail. These rectangularly shaped extensions provide a sturdy structure of sumcient depth throughout the length of ,each .extension to withstand the blows lreceived when the -window sashes are 'opened forcibly. Y

As shown in Figure 5, it will be seen that a plate 3l, preferably made of metal, is' secured to the rail I3. The plate 3l has an aperture in line with the aperture '20 in the rail I3. The plate 3I is preferably secured to the rail I3 by screws 32. receive a vertically movable locking bolt 34, slid- Theplate 3I has an aperture 33 to able therein. The locking bolt 34 is preferably rectangular in cross-section and is adapted to enter into either one of two rectangular apertures 35, 3l in the rail I1 for locking the swinging sash in open or closed position.

When washing a sash or moving it from open or closed position it is merely necessary to raise the locking bolt and when the sash has been swung to the desired reverse position the locking bolt automatically falls into one of the apertures 35. To permit the ready entrance of the locking bolt 34 into either of the apertures 35, preferably provided by metal sleeves the entering end of they locking bolt'is preferably beveled.

As lshown in Figure 2. the lower end of the window I9 has a cut-out portion 31, the said cutout portion being of suincient depth to permit the upper slidable frame II to enter therein and causing the swinging sash I5 to be positioned below the lower surface of the lower slidable frame when in topmost raised position and permitting the swinging of the upper sash frame at a convenient low operating levelthe same as the level of operation of the lower sash frame. This expedient of the provision of the cut-out portion 31 tends also to increase vision and at the same time saves on sash construction.

In order to swing the sash of the lower slidable frame I2'to reverse position both window frames must be in closed position. A latch on the upper rail ofthe lower sash is unnecessary to use when reversing and washing thel window sash though it is placed in its usual position for the prevention of burglary.

Any well known vstandard latch which is not necessary to turn in order to release, can beA additionally used on the VerticaI-rabbeted sides of the frames.- 'Ihis latch serves the added purpose of preventing the window from vibrating and rattling.

It is to be noted that the contacting surfaces at the line of abutment 29 are preferably made of metal and are of sunlcient depth so that the window sashes when reversed to the maximum swing, will contact each other in concealed position and prevent the window frames from being dented by being jarred against the visible outside surface of one of the rectangular extensions. It prevents hitting the side of one of the rails or'the side of one of the extensions.

As best shown in Figure 3. the central end portion of the longer vertical extension, which extends beyond the pivot, rides in the cavity. The thicker or wider the frame and rails, the greater the cavity can be made and the greater the length the said central end portion can be made.

As shown inFigure 6, I have provided a modified pivotal mounting 39, comprising a pivot 39 ilxed in the rail I1. The pivot 39 has an aperture 40. -A coil spring 4I is mounted directly on and in contacting relation with the pivot 39 and has one of its ends 42 anchored in the aperture 4l. The rail I3 has a metal sleeve 43 ilxed therein and being centrally positioned with the pivot 39. The sleeve has a slot 44 in which the other end of the spring is anchored.

It is to be noted that eachl sash frame is mounted on two pivots. When a spring-actuated sash is swung to open position the springs will become tensioned and the locking bolt will automatically fall into one of the apertures 39 and lock the sash'against swinging back to closed position by action of the tensioned springs. Upon release of the locking bolt 34 the displaced sash wul be automatically brought back to its normal closed position, when the locking bolt Il automatically falls linto the other aperture 35,

and locks the sash in closed position. Under operating conditions the springs will be only slightly tensioned, so that the window sash will be slowly returned to the normal closed position.

It is to be noted that each pair of the rails I3 and i1 are interchangeable; that is, while I have shown the rails as positioned with the abutting surfaces contacting in a, single plane, when facing the inside of the room, I may reverse them so that this single plane arrangement may be visible from the outside of the' room. It is also ...and designed to fall into recesses (not shown).

The handles are flush with the outer surfaces of the swinging sash frames to permit up and down movements without encountering any ob struction to their movements. 1

In accordance with the patent statutes we have described and illustrated the preferred embodiment of our invention. but it will be understood that various changes and modifications can be made therein without departing from the spirit of the invention as dened by the appended claims.
